Z~is 10 acre site consists of Newlin series soils, specifically, Newlin <br /> gravelly sandy loam, 8 to 30~ slopes. The Soil Conservation Service Castle <br />' RocN: Soil Survey has this to say about these soils: <br /> NEW[JIJ SERIES: The Newlin series consists of well-drained soils. These <br />' soils formed in alluvial soil materials derived faun mixed sources and <br /> are moderately deep over unconformable very gravelly sand. They are roll- <br />' ing to moderately steep soils on uplands and side slopes. Slopes are 8 <br />to 30 <br />ercent <br />The ve <br />tati <br />n i <br />m <br />i <br />l <br />td <br />d t <br />ll <br />b <br />t > <br />l <br />- <br /> p <br />. <br />ge <br />o <br />s <br />a <br />n <br />y n <br />an <br />a <br />grasses, <br />u <br />n p <br />a <br /> ces mountain~nahogany, Gambol oak, and scluawbush are present. Elevations <br />' are 5,500 to 6,600 feet. Annual prxipitation is 15 to 19 inches. Mean <br /> annual soil temperature is 49° to 51° F., and the frost-free season is <br />' 120 to 135 days. <br /> In a representative profile the surface layer is dark grayish-brown <br />' gravl~.lly sandy loam about 8 inches thick. The sl~bsoil, about 14 inches <br /> tt:ic.c, is broom and light-bmwn gravelly sandy clay loam and gravelly sandy <br /> loam. The underlying material is brown ch-yellow very gravelly sand that <br /> extends to a depth of 60 inches or mere. Runoff is medium. `"he erosion <br /> hezard is sligh*_ to moderate. <br /> Newlin soils have moderate permeability. Available water. capacity <br />' is 1<xv. Plants penetrate to a depth of 60 inches or more. <br /> Most areas of Newlin soils are in native grasses and are used for <br /> grazing livestock and for wildlife habitat. Where gravel beds aL~ thick, <br /> theses soils are sources of gravel for construction. <br /> •te~t* <br />' Vegetation on site consists primarii.y of noxious weeds (Russian Knap- <br /> w~edl. Sane native grasses exist, but dominance is being exerted by the <br />' weeds. Vegetztive cover is sparse primarily because the available topsoil <br />
